119701-63-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119701-63-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,7,0 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 119701-63:
(8*1)+(7*1)+(6*9)+(5*7)+(4*0)+(3*1)+(2*6)+(1*3)=122
122 % 10 = 2
So 119701-63-2 is a valid CAS Registry Number.

Base-catalysed Reaction of Formaldehyde with 1,3-Diaryl-1,3-propanediones
Joglekar, S. J.,Samant, S. D.
, p. 587 - 588 (2007/10/02)
Instead of undergoing the Mannich reaction, 1,3-diaryl-1,3-propanediones (1) yield 2-aroyl-1,5-diaryl-1,5-pentanediones (4) via base-catalysed cleavage.The cleaved product is isolated as the corresponding acid.A suitable mechanism has been discussed.
